Why do some networks keep working when there is a failure, but others stop completely? This is about high availability in network design. Many engineers think high availability means just adding backup links. But it is more than that. It is about how fast the network can detect a failure, how it reacts, and how much of the network is affected. A good design should make sure the problem stays small. It should not affect the whole network. We use things like BFD, FRR, CoPP, Carrier-delay, debounce-timers, ECMP, Graceful Restart etc. and design techniques that limit failure impact. But the most important thing is the design decisions—not the features. For example, just adding extra links without thinking can create loops or make the network slower to recover. High availability is not just about adding more. It is about designing smarter. If you're preparing for the CCDE or working as a network designer, these are the things you need to think about. #OrhanErgun #networkdesign #ccde #networkarchitecture

Multicast isn’t dead, in fact, it’s essential for networks that need to efficiently deliver the same data to many receivers. Whether it's live video streaming, financial market data, IPTV, or replication in data centers, multicast allows you to scale without wasting bandwidth. When combined with MPLS (like mVPN), it becomes even more powerful, enabling service providers and large enterprises to deliver multicast across complex, multi-tenant environments. For network engineers, understanding multicast means: -- More efficient designs -- Better traffic engineering -- The ability to support real-time, high-bandwidth services If you want to build a solid foundation in both IP and MPLS multicast, Orhan Ergun’s IP and MPLS Multicast course: buff.ly/Wast7fk is one of the best ways to learn it, real-world focused, deeply technical, and incredibly relevant. #multicast #mpls #ccie #orhanergun

I am blessed to have an amazing family. My brother Michael has always been a gifted carpenter. He just finished my kitchen remodel. It was a complex project as it was a complete tear down. Just an amazing transformation. instagram.com/reel/C4GsgDVpC…
